GM tells NHTSA pickup truck electronic glitch is 'inconsequential'

General Motors has been enduring some serious problems with recalls recently, and it is hoping to avoid launching another major safety campaign. 200,921 2014 Chevrolet Silverado and GMC Sierra pickups are under the microscope due to a rare problem with their instruments, an issue GM calls calls "inconsequential to motor vehicle safety." The Detroit-based automaker believes that the glitch is so minor that it has filed a petition with the National Highway Traffic Safety Administration asking the government safety watchdog for permission to pass on recalling the vehicles.
The fault at issue can occasionally cause the instrument cluster to reset when drivers use the steering wheel controls to browse songs from an external media device connected to the truck's USB ports. If a song's title information exceeds 2,000 bytes, according to The Detroit News, then the instrument panel can reset, which in turn causes the gauges, shift position indicator and cruise control telltale to turn off briefly. When rebooting, other instrument panel lights may briefly illuminate without their functions actually being activated. GM claims that if this does happen, the instrument display lights go out for about 1.5 seconds and the bulb check lasts a further five seconds. However, this snafu has no actual affect on the truck's operation. The glitch is present in trucks built between January 29, 2013, and October 28, 2013.

GM Ultium tech can scavenge heat from everywhere, even you

GM likes to give us tidbits about its Ultium platform from time to time, and today it’s telling us about the platformÂ’s ability to capture waste heat from the propulsion system. In addition to capturing from the propulsion system, it can also capture humidity from both inside and outside the vehicle and even from passengersÂ’ body heat. Yes, you, your family and/or your friends are a usable heat source as far as GM EVs are concerned. It then deploys the heat in an advantageous way. If at this point, youÂ’re screaming, "Heat pump!" youÂ’d be right. WeÂ’re talking about an elaborate heat pump system that GM is using for its Ultium-based vehicles. Every Ultium-based GM vehicle gets this system that is covered by 11 patents and four publications. The waste heat it collects is used in a number of ways, but its primary use is to heat the cabin quickly and efficiently. GM claims it can heat the cabin of its Ultium-based vehicles quicker than vehicles with traditional internal combustion engines. Plus, when put to use, GM claims that using the heat pump provides its EVs with up to 10% more range than theyÂ’d have without. Beyond heating the cabin, the heat pump is capable of putting waste heat to use by preheating the battery prior to charging so that you can charge quicker. The system can even cool the propulsion system in preparation for Watts to Freedom (WTF) launch control starts. GM says this was vital in helping the Hummer EV achieve its bonkers 0-60 mph time of about 3 seconds. “Having a ground-up EV architecture gives us the freedom to build in standard features like UltiumÂ’s energy recovery capabilities,” said Doug Parks, GM executive VP of global product development, purchasing and supply chain. “This helps us squeeze more efficiency, performance and overall customer benefit out of our EVs.” GM says itÂ’s been developing heat pump technology since the EV1 and its heat pump. This is the modern evolution of that technology, and GM says itÂ’s going to be implemented in every Ultium-based vehicle as a standard feature.

GM program sees dealers taking on way more loaner cars

Given the volume of vehicles we're talking about, this is a significant development for GM's bottom line. Bring your car into the dealership for service, and you may need a loaner car in exchange. And with so many recalls being carried out, that means a lot of loaners – especially at General Motors dealerships. That could be one of the reasons why GM is massively expanding its loaner fleet program. While many Chevrolet and Buick-GMC dealerships have an on-site rental car location operated by a third party like Enterprise (which may or may not provide a GM vehicle), others manage their own loaner fleets. But while the range of dealerships operating such fleets was once small, reports Automotive News, the number has been growing rapidly: from the locations responsible for only 20 percent of those brands' sales two years ago to about 90 percent today. The impetus for that growth comes down to a massive expansion of GM's Courtesy Transportation Program. The initiative encourages dealers to ramp up their loaner fleet to a maximum size determined by GM, with a mix determined by the dealer itself, so that a showroom in Texas can be bolstered with a fleet of pickup trucks and a dealer in California can employ more Volt and Camaro Convertible loaners. The dealership gets a $500 credit for each vehicle its puts in its fleet, and can use those vehicles as loaners for service customers, as multi-day test drivers or to rent out separately. The vehicles remain in the dealer's fleet for 90 days or 7,500 miles, then they can be sold as used, but with new-car incentives. The dealer gets a fleet of loaners, customers get to use the loaners, try out a new car overnight or buy a barely used car with attractive incentives, and GM gets to clock more sales. But therein lies the kicker: the automaker counts the dispatch of the loaner new vehicle to the dealership as a new-car sale, which could end up distorting its sales figures. Counting loaner vehicles as sold vehicles is something of an industry-standard practice, but given the volume of vehicles we're talking about, this is a significant development for GM's bottom line. One dealership - Paddock Chevrolet in Kenmore, NY, for example - had no loaner fleet two years ago, but now runs a fleet of 50 vehicles. Multiply that by the 4,000 or so dealers GM has across America and you're talking about the potential for hundreds of thousands of these sorts of sales.
